Which is the most acidic hydrogen in the following compound? V o H HAI CN H HII IV H Hн A. III B. I C. II D.V E. IV

science chemistry

Answer 1

Answer #1

Because of the presence of CN and C=O groups, electron density of C-H bond (number I) decreases significantly which increases the acidity.

C=O and CN pulls electron density by -I effect (inductive effect).

thus I H is most acidic.
option B is correct.
